I have a GPS 1PPS signal available and would like to use it to distribute time across my home network. The more accurate the better. GPS ----> single-board computer ------> several PTP client hosts 1PPS ethernet I see that the TI AM355x boards like the Beaglebone Black have an ethernet driver with hardware timestamp support, but I also found some references on this mailing list to a silicon bug affecting the PTP clock? Assuming that's still the case, what limitations does it impose? I haven't procured any hardware yet. Is there another animal- or fruit-board SBC with better PTP support that I should be looking at? If I do go with the Beaglebone, will a recent mainline kernel get me everything I need (current PTP drivers, PPS input on a GPIO pin)? Thanks, Mark |
